137-654: The Fairey Firefly is a Second World War -era carrier-borne fighter aircraft and anti-submarine aircraft that was principally operated by the Fleet Air Arm (FAA). It was developed and built by the British aircraft manufacturer Fairey Aviation Company . Development of the Firefly can be traced back to pair of specifications issued by the British Air Ministry in 1938, calling for new naval fighter designs. Designed to

Two ex-Swedish Fireflies moved to IWM Duxford, Cambridgeshire in 2003. Acquired by the Aircraft Restoration Company, they were in Royal Navy service from 1944 and 1946, and then converted to target tugs for gunnery training in 1950 and 1954.

The aircraft returned to the UK in 1964 to go on display at the Skyframe Aircraft Museum, and was acquired by Imperial War Museum in 1979. The museum returned Z2033 to its original MkI configuration, and repainted

The U.S. followed the British development closely and when the Mk.V was designed, the Americans followed suit with the A/N M3 but unreliability continued. After the war the United States Air Force (USAF) adopted a version of the M3 cannon as
959-577: A concept that was quickly taken up by other companies. Notable among the resulting designs was the Swiss Oerlikon FF S , which was based on the Becker but introduced a number of improvements. In the 1930s, Hispano-Suiza was asked to develop a 20 mm cannon to fire through the propeller shaft (as a moteur-canon SS) of a gear-reduction inline aviation engine like the Hispano-Suiza 8BeC . They took out
1096-528: A conventional and a " turret fighter ". The performance requirements for both was to be able to attain a speed of 275 knots while flying at 15,000 ft (4,600 m) and carrying an armament, for the conventional fighter, of eight 0.303 in (7.7 mm) Browning machine guns or four 20 mm (0.79 in) Hispano cannon . This aircraft would replace the Fairey Fulmar , which had been viewed as an interim design. These specifications were updated during
1233-461: A fighter. The limitations of a single engine in a relatively heavy airframe reduced its performance, but the Firefly proved to be a fairly sturdy, long-ranged, and docile aircraft during carrier operations. The Fairey Firefly served in the Second World War as a fleet fighter. During the post-war era, it was soon superseded in the fighter role by the arrival of more modern jet aircraft , thus

In 1940, Hispano-Suiza was developing a belt-feeding system, as well as derivatives of the HS.404 in heavier calibres such as 23 mm but these projects were halted with the German occupation of France. Before the Second World War, the United Kingdom had embarked on
1507-663: A license on the Oerlikon FF S and made minor modifications to produce the Hispano-Suiza Automatic Cannon Type HS.7 and HS.9. Shortly after production began, the Hispano-Suiza and Oerlikon companies disagreed over patent rights and their business connection came to an end. In 1933, the chief engineer of Hispano-Suiza, Marc Birkigt , began work on the design of a new weapon to replace the Oerlikon contract, based on

As a ground vehicle-mounted gun, either anti-aircraft or as a general-purpose autocannon, the HS.404 lasted into the 1960s. A powered turret variant is still in production in Honduras and is used as a light anti-aircraft gun by the army and navy in several nations. The AN/M3 was developed into the Mk12 Colt 20 mm automatic cannon, one of

Based upon the feedback of veteran pilots, Canada opted to acquire the Firefly over opposition that favoured procuring American aircraft instead. As a stop-gap measure, Royal Navy Fireflies were loaned while more advanced purpose-built aircraft were being constructed. Between 1946 and 1954,
2192-514: A pretext to initiate the invasion. The first German attack of the war came against the Polish defences at Westerplatte . The United Kingdom responded with an ultimatum for Germany to cease military operations, and on 3 September, after the ultimatum was ignored, Britain and France declared war on Germany. During the Phoney War period, the alliance provided no direct military support to Poland, outside of
2329-666: A pretext to worsen relations. On 29 August, Hitler demanded that a Polish plenipotentiary immediately travel to Berlin to negotiate the handover of Danzig , and to allow a plebiscite in the Polish Corridor in which the German minority would vote on secession. The Poles refused to comply with the German demands, and on the night of 30–31 August in a confrontational meeting with the British ambassador Nevile Henderson , Ribbentrop declared that Germany considered its claims rejected. On 1 September 1939, Germany invaded Poland after having staged several false flag border incidents as

Its first use was in the Westland Whirlwind of 1940 and later in the more powerful Bristol Beaufighter , providing the Royal Air Force (RAF) with powerful cannon-armed interceptors. The experience of the Battle of Britain had shown

The Soviet Union invaded Finland in November 1939, and was subsequently expelled from the League of Nations for this crime of aggression. Despite overwhelming numerical superiority, Soviet military success during the Winter War was modest, and the Finno-Soviet war ended in March 1940 with some Finnish concessions of territory .

Immediately afterwards, Hitler ordered the attack to proceed on 26 August, but upon hearing that the United Kingdom had concluded a formal mutual assistance pact with Poland and that Italy would maintain neutrality, he decided to delay it. In response to British requests for direct negotiations to avoid war, Germany made demands on Poland, which served as

Firing a 20 mm calibre projectile, it delivered a significant load of explosive from a relatively light weapon. This made it an ideal anti-aircraft weapon for mounting on light vehicles, as well as a fighter aircraft gun, supplementing or replacing

The HS.404 was produced by the French subsidiary of Hispano-Suiza, and under license by a variety of companies in other countries. The first widely used 20 mm aircraft cannon was the Becker model , introduced into German service in World War I . The Becker introduced the advanced primer ignition blowback (API) design for autocannons,

The situation became a crisis in late August as German troops continued to mobilise against the Polish border. On 23 August the Soviet Union signed a non-aggression pact with Germany, after tripartite negotiations for a military alliance between France, the United Kingdom, and Soviet Union had stalled. This pact had

4384-520: The Hawker Hurricane and Supermarine Spitfire had shown a tendency for the gun to jam during combat manoeuvres, leading to some official doubt as to the suitability of cannon as the sole main armament. This led to the Air Ministry for a brief period specifying 12-machine gun armament for new fighters. A suitable belt-feeding system was developed by Martin-Baker and the new design was adopted by

By the end of the 1950s, many operators were disposing of their remaining Fireflies, typically as scrap . In the late 1940s, the Royal Netherlands Navy deployed a Firefly squadron to the Dutch East Indies, as part of the forces countering Indonesian nationalists. When talks broke down in July 1947, the Dutch launched multiple air strikes. Three Fireflies were shot down by ground fire.

Both Italy and Ethiopia were member nations, but the League did little when the former clearly violated Article X of the League's Covenant . The United Kingdom and France supported imposing sanctions on Italy for the invasion, but the sanctions were not fully enforced and failed to end the Italian invasion. Italy subsequently dropped its objections to Germany's goal of absorbing Austria . When civil war broke out in Spain, Hitler and Mussolini lent military support to

These were complemented with four 0.303 calibre (7.7 mm) or two 0.50 calibre (12.7 mm) machine guns. The British were concerned their production would be inadequate and licensed production of
10138-452: The Royal Navy putting three Italian battleships out of commission after a carrier attack at Taranto , and neutralising several more warships at the Battle of Cape Matapan . Italian defeats prompted Germany to deploy an expeditionary force to North Africa; at the end of March 1941, Rommel 's Afrika Korps launched an offensive which drove back Commonwealth forces. In less than a month, Axis forces advanced to western Egypt and besieged
10275-584: The Soviet Union occupied the entire territories of Estonia, Latvia and Lithuania, as well as the Romanian regions of Bessarabia, Northern Bukovina, and the Hertsa region . In August 1940, Hitler imposed the Second Vienna Award on Romania which led to the transfer of Northern Transylvania to Hungary. In September 1940, Bulgaria demanded Southern Dobruja from Romania with German and Italian support, leading to
10412-790: The Soviet Union , opening the Eastern Front and initially making large territorial gains. Japan aimed to dominate East Asia and the Asia-Pacific , and by 1937 was at war with the Republic of China . In December 1941, Japan attacked American and British territories in Southeast Asia and the Central Pacific , including Pearl Harbor in Hawaii , which resulted in the US and the UK declaring war against Japan, and
10549-621: The Soviet Union and Mongolia . The Japanese doctrine of Hokushin-ron , which emphasised Japan's expansion northward, was favoured by the Imperial Army during this time. This policy would prove difficult to maintain in light of the Japanese defeat at Khalkin Gol in 1939, the ongoing Second Sino-Japanese War and ally Nazi Germany pursuing neutrality with the Soviets. Japan and the Soviet Union eventually signed
10686-738: The Soviet Union should be eliminated and aimed for the conquest of Ukraine , the Baltic states and Byelorussia . However, other senior German officials like Ribbentrop saw an opportunity to create a Euro-Asian bloc against the British Empire by inviting the Soviet Union into the Tripartite Pact. In November 1940, negotiations took place to determine if the Soviet Union would join the pact. The Soviets showed some interest but asked for concessions from Finland, Bulgaria, Turkey, and Japan that Germany considered unacceptable. On 18 December 1940, Hitler issued
10823-451: The US dropped the first atomic bombs on Hiroshima and Nagasaki on 6 and 9 August. Faced with an imminent invasion of the Japanese archipelago , the possibility of further atomic bombings, and the Soviet declaration of war against Japan and its invasion of Manchuria , Japan announced its unconditional surrender on 15 August and signed a surrender document on 2 September 1945 , marking
10960-568: The United Kingdom and France guaranteed their support for Polish independence ; when Italy conquered Albania in April 1939, the same guarantee was extended to the Kingdoms of Romania and Greece . Shortly after the Franco - British pledge to Poland, Germany and Italy formalised their own alliance with the Pact of Steel . Hitler accused the United Kingdom and Poland of trying to "encircle" Germany and renounced
11097-538: The United Kingdom attacked on 3 July in an attempt to prevent its seizure by Germany. The air Battle of Britain began in early July with Luftwaffe attacks on shipping and harbours . The German campaign for air superiority started in August but its failure to defeat RAF Fighter Command forced the indefinite postponement of the proposed German invasion of Britain . The German strategic bombing offensive intensified with night attacks on London and other cities in
11234-455: The United Kingdom. The Germans turned south against the weakened French army, and Paris fell to them on 14 June. Eight days later France signed an armistice with Germany ; it was divided into German and Italian occupation zones , and an unoccupied rump state under the Vichy Regime , which, though officially neutral, was generally aligned with Germany. France kept its fleet, which
11371-640: The United States was assisting China and the Western Allies, and had amended the Neutrality Act to allow "cash and carry" purchases by the Allies. In 1940, following the German capture of Paris, the size of the United States Navy was significantly increased . In September the United States further agreed to a trade of American destroyers for British bases . Still, a large majority of the American public continued to oppose any direct military intervention in

11645-590: The Yellow River ; this manoeuvre bought time for the Chinese to prepare their defences at Wuhan , but the city was taken by October. Japanese military victories did not bring about the collapse of Chinese resistance that Japan had hoped to achieve; instead, the Chinese government relocated inland to Chongqing and continued the war. In the mid-to-late 1930s, Japanese forces in Manchukuo had sporadic border clashes with
11782-715: The aircraft as 'DK431' of 1771 Naval Air Squadron, as operated in the Pacific in July 1945. Z2033 was loaned to the Fleet Air Arm Museum for display between 2000 and August 2023, but the aircraft is now on display again at Imperial War Museum Duxford . Firefly WB271 was destroyed in July 2003 during an aerobatic air display at the Imperial War Museum in Duxford, Cambridgeshire – Europe's largest display of vintage warplanes. There are two airworthy Fireflies at present: WB518
11919-641: The aircraft used during the Second World War was the Firefly Mk I, which was used in all theatres of operations. During March 1943, the first Firefly Mk Is were delivered to the FAA but these did not enter operational service until July 1944, at which point they equipped 1770 Naval Air Squadron aboard HMS Indefatigable . The first operations were flown in the European theatre where Fireflies carried out numerous armed reconnaissance flights and anti-shipping strikes along
12056-501: The aircraft was 4,000 lb (1,800 kg) heavier than the preceding Fulmar (largely due to the adoption of the heavier Griffon engine and the armament of two 20 mm (0.79 in) Hispano cannon in each wing), the Firefly was 40 mph (64 km/h) faster due to improved aerodynamics , as well as the increased power of the Griffon IIB engine, being capable of generating a maximum of 1,735 hp (1,294 kW). The Firefly
12193-502: The anti-submarine role until 1956 when front line aircraft were replaced by the Fairey Gannet . There are approximately 24 Fairey Fireflies surviving worldwide, including three airworthy examples and at least one other being restored to flying condition. The Fleet Air Arm Museum holds VH127, a TT4, which is on public display at Yeovilton. The Imperial War Museum owns one of the oldest surviving Fireflies, serial number Z2033. Built as
12330-471: The batteries of eight rifle-calibre M1919 Browning machine guns to be inadequate and prompted the adoption of autocannon armament for the primary portion of RAF fighters. The Beaufighter highlighted the need for a belt feed mechanism; as a night fighter the 60-round drums needed to be replaced in the dark by the Radar / Wireless Operator, often while the aircraft was manoeuvring. The early trial installations in
12467-514: The bolt was locked during firing, it could be lighter than that of the Oerlikon, thus facilitating an increase in rate of fire to 700 rounds per minute (rpm), a gain of about 200 rpm. In 1938, Birkigt patented it and started production in their Geneva factory. The HS.404's predecessor, the Oerlikon type S auto-cannon, was rather heavy, and the movement of the heavy bolt made it best suited in static and maritime anti-aircraft defence. The lighter bolt of
12604-502: The capital Nanking in December 1937. After the fall of Nanking, tens or hundreds of thousands of Chinese civilians and disarmed combatants were murdered by the Japanese . In March 1938, Nationalist Chinese forces won their first major victory at Taierzhuang , but then the city of Xuzhou was taken by the Japanese in May. In June 1938, Chinese forces stalled the Japanese advance by flooding
12741-499: The conflict as many of its aircraft did not feature cannons when configured for anti-submarine warfare. Despite several incidents of aircraft being struck by anti-aircraft fire , the Firefly proved to be relatively rugged. The type was routinely used for strike operations against targets such as bridges and railway lines to damage North Korean logistics and communications. As the war went on, pilots developed new low-level dive-bombing techniques to achieve greater accuracy. Combat use of
12878-403: The conflict well into 1941. In December 1940, Roosevelt accused Hitler of planning world conquest and ruled out any negotiations as useless, calling for the United States to become an " arsenal of democracy " and promoting Lend-Lease programmes of military and humanitarian aid to support the British war effort; Lend-Lease was later extended to the other Allies, including the Soviet Union after it
13015-408: The contemporary FAA concept of a two-seat fleet reconnaissance/fighter, the pilot and observer were positioned at separate stations. In flight, the Firefly was superior in terms of both performance and firepower to its predecessor, the Fairey Fulmar . Due to a protracted development, the type only entered operational service towards the end of the conflict, at which point it was no longer competitive as
13152-515: The creation of a " New Roman Empire ". Adolf Hitler , after an unsuccessful attempt to overthrow the German government in 1923, eventually became the Chancellor of Germany in 1933 when Paul von Hindenburg and the Reichstag appointed him. Following Hindenburg's death in 1934, Hitler proclaimed himself Führer of Germany and abolished democracy, espousing a radical, racially motivated revision of
13289-579: The directive to prepare for an invasion of the Soviet Union. Hispano-Suiza HS.404 The HS.404 is an autocannon originally designed by and produced by the Swiss arm of the Spanish/Swiss company Hispano-Suiza in the mid-1930s. Production was later moved to the French arm of Hispano-Suiza. It was widely used as an aircraft, naval and land-based weapon by French, British, American and other military services, particularly during World War II . The cannon
13426-789: The dissolution of the Austro-Hungarian, Ottoman, and Russian Empires. To prevent a future world war, the League of Nations was established in 1920 by the Paris Peace Conference . The organisation's primary goals were to prevent armed conflict through collective security, military, and naval disarmament , as well as settling international disputes through peaceful negotiations and arbitration. Despite strong pacifist sentiment after World War I , irredentist and revanchist nationalism had emerged in several European states. These sentiments were especially marked in Germany because of
13563-683: The end of May completed the German conquest of the Balkans. Partisan warfare subsequently broke out against the Axis occupation of Yugoslavia , which continued until the end of the war. In the Middle East in May, Commonwealth forces quashed an uprising in Iraq which had been supported by German aircraft from bases within Vichy-controlled Syria . Between June and July, British-led forces invaded and occupied
13700-463: The end of the war. World War II changed the political alignment and social structure of the world, and it set the foundation of international relations for the rest of the 20th century and into the 21st century. The United Nations was established to foster international cooperation and prevent conflicts, with the victorious great powers—China, France, the Soviet Union, the UK, and the US—becoming
13837-566: The first step of what its government saw as the country's right to rule Asia , staged the Mukden incident as a pretext to invade Manchuria and establish the puppet state of Manchukuo . China appealed to the League of Nations to stop the Japanese invasion of Manchuria. Japan withdrew from the League of Nations after being condemned for its incursion into Manchuria. The two nations then fought several battles, in Shanghai , Rehe and Hebei , until
13974-419: The following year, while several British manufacturers tendered their ideas. Further changes to the official specification followed, such as the turret fighter specification being eliminated, while a modified specification was issued to cover single and dual-seat fighters capable of 330 and 300 kn (610 and 560 km/h; 380 and 350 mph) respectively. Fairey offered designs that could accommodate either
14111-843: The former Chinese imperial capital of Peking after instigating the Marco Polo Bridge incident , which culminated in the Japanese campaign to invade all of China. The Soviets quickly signed a non-aggression pact with China to lend materiel support, effectively ending China's prior cooperation with Germany . From September to November, the Japanese attacked Taiyuan , engaged the Kuomintang Army around Xinkou , and fought Communist forces in Pingxingguan . Generalissimo Chiang Kai-shek deployed his best army to defend Shanghai , but after three months of fighting, Shanghai fell. The Japanese continued to push Chinese forces back, capturing
14248-420: The ground by the aircraft armourers before flight, the pneumatic cocking mechanism used previously being regarded as unnecessary weight and detrimental to aircraft performance; any stoppage in flight made the gun unusable until it could be cleared on the ground. The misfires also had the tendency to cause aircraft with wing-mounted guns to yaw away from the wing with the failed gun when the guns were fired, due to
14385-555: The guns remained unsuitable. The U.S. Navy had been trying to switch to using cannon on all its combat aircraft throughout the war but the conversion never occurred. As late as December 1945 the U. S. Army Chief of Ordnance was still attempting to complete additional changes to the design to allow it to enter service. Some variations of the 20 mm guns used on the Lockheed P-38 Lightning aircraft were produced by International Harvester . The P-38's nose-mounted M2 featured
14522-476: The introduction of revolver cannon , based on the prototype versions of the un-built German wartime Mauser MG 213 design. The British introduced the powerful revolving 30 mm ADEN cannon in most of their post-war aircraft, while the French used the similar DEFA cannon , firing similar ammunition. The USAF introduced the 20 mm M39 cannon to replace the M24, while the Navy combined the original Hispano design with
14659-512: The invasion of the Ethiopian Empire (also known as Abyssinia ) by the armed forces of the Kingdom of Italy ( Regno d'Italia ), which was launched from Italian Somaliland and Eritrea . The war resulted in the military occupation of Ethiopia and its annexation into the newly created colony of Italian East Africa ( Africa Orientale Italiana , or AOI); in addition it exposed the weakness of
14796-522: The main weapons on boats of the Mobile Riverine Force in the Vietnam War and also used on some larger amphibious ships. The Hispano fired a 130 grams (4.586 oz) 20 mm diameter projectile from a 110 mm (4.331 in) long casing, the whole round weighing 257 g (9.065 oz). Lengths of the projectiles varied with type but were set to variable depth in the casing to produce
14933-759: The other was traded to the Aviodrome Museum in the Netherlands for a Spitfire. As well as the Canadian Warplane Heritage's ex-Australian Firefly, two other Fireflies are known to exist in Canada: one is at the Canada Aviation and Space Museum in Ottawa and another is being restored at the Shearwater Aviation Museum at Eastern Passage (near Dartmouth), Nova Scotia. Both are Mk I models that served in
15070-497: The permanent members of its security council . The Soviet Union and the United States emerged as rival superpowers , setting the stage for the Cold War . In the wake of European devastation, the influence of its great powers waned, triggering the decolonisation of Africa and Asia . Most countries whose industries had been damaged moved towards economic recovery and expansion . World War II began in Europe on 1 September 1939 with
15207-571: The political European map with the defeat of the Central Powers —including Austria-Hungary , Germany , Bulgaria , and the Ottoman Empire —and the 1917 Bolshevik seizure of power in Russia , which led to the founding of the Soviet Union. Meanwhile, the victorious Allies of World War I , such as France, Belgium, Italy, Romania, and Greece, gained territory, and new nation-states were created out of
15344-583: The port of Tobruk . By late March 1941, Bulgaria and Yugoslavia signed the Tripartite Pact ; however, the Yugoslav government was overthrown two days later by pro-British nationalists. Germany and Italy responded with simultaneous invasions of both Yugoslavia and Greece , commencing on 6 April 1941; both nations were forced to surrender within the month. The airborne invasion of the Greek island of Crete at
15481-505: The production of ammunition . When delivered, the guns proved to be extremely unreliable and suffered a considerable number of misfires due to the round being lightly struck by the firing pin . The British were interested in using this weapon to ease the demand on production in England but after receiving the M1 they were disappointed. British wing-mounted fighter weapons by this period were cocked on
15618-412: The projectile is siphoned off and operates a piston that drives a rod, running along the top of the barrel, back against a cam on the bolt, unlocking it and allowing the remaining high pressure gases in the barrel to propel it and the spent cartridge backwards in a delayed sequence that allows the bolt to remain closed until the projectile has exited from the barrel. This maximizes muzzle velocity and since
15755-693: The remainder of Czechoslovakia and subsequently split it into the German Protectorate of Bohemia and Moravia and a pro-German client state , the Slovak Republic . Hitler also delivered an ultimatum to Lithuania on 20 March 1939, forcing the concession of the Klaipėda Region , formerly the German Memelland . Greatly alarmed and with Hitler making further demands on the Free City of Danzig ,
15892-458: The significant territorial, colonial, and financial losses imposed by the Treaty of Versailles . Under the treaty, Germany lost around 13 percent of its home territory and all its overseas possessions , while German annexation of other states was prohibited, reparations were imposed, and limits were placed on the size and capability of the country's armed forces . The German Empire was dissolved in
16029-494: The start or prelude to World War II. The exact date of the war's end also is not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 15 August 1945 ( V-J Day ), rather than with the formal surrender of Japan on 2 September 1945, which officially ended the war in Asia . A peace treaty between Japan and the Allies was signed in 1951. A 1990 treaty regarding Germany's future allowed
16166-521: The strong Maginot Line fortifications on the Franco-German border, Germany directed its attack at the neutral nations of Belgium , the Netherlands , and Luxembourg . The Germans carried out a flanking manoeuvre through the Ardennes region, which was mistakenly perceived by the Allies as an impenetrable natural barrier against armoured vehicles. By successfully implementing new Blitzkrieg tactics,
16303-577: The two wars became World War II in 1941. Other proposed starting dates for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939. Others view the Spanish Civil War as
16440-454: The unequal recoil , throwing off the pilot's aim. In April 1942 a copy of the British Mk.II was sent to the U.S. for comparison. The British version used a slightly shorter chamber and did not have the same problems as the U.S. version of the cannon. The U.S. declined to modify the chamber of their version but nonetheless made other modifications to create the unreliable M2. By late 1942 the USAAF had 40 million rounds of ammunition stored but
16577-407: The war were not fulfilled in the peace settlement. From 1922 to 1925, the Fascist movement led by Benito Mussolini seized power in Italy with a nationalist, totalitarian , and class collaborationist agenda that abolished representative democracy, repressed socialist, left-wing, and liberal forces, and pursued an aggressive expansionist foreign policy aimed at making Italy a world power, promising
16714-475: The war. Germany annexed western Poland and occupied central Poland ; the Soviet Union annexed eastern Poland ; small shares of Polish territory were transferred to Lithuania and Slovakia . On 6 October, Hitler made a public peace overture to the United Kingdom and France but said that the future of Poland was to be determined exclusively by Germany and the Soviet Union. The proposal was rejected and Hitler ordered an immediate offensive against France, which
16851-404: The west halted the German advance for several days, but it was outflanked and encircled by the Wehrmacht . Remnants of the Polish army broke through to besieged Warsaw . On 17 September 1939, two days after signing a cease-fire with Japan , the Soviet Union invaded Poland under the supposed pretext that the Polish state had ceased to exist. On 27 September, the Warsaw garrison surrendered to
16988-419: The wings, which was considered to be relatively heavy armament for the era. According to pilots, the general handling of the Firefly was relatively well-balanced, but a level of physical strength was required to effectively execute aerobatics . During 1942, handling and performance trials were first undertaken at RAF Boscombe Down by Admiralty test pilots Mike Lithgow and Roy Sydney Baker-Falkner . By 1944,
17125-483: The world order , and soon began a massive rearmament campaign . France, seeking to secure its alliance with Italy, allowed Italy a free hand in Ethiopia , which Italy desired as a colonial possession. The situation was aggravated in early 1935 when the Territory of the Saar Basin was legally reunited with Germany, and Hitler repudiated the Treaty of Versailles, accelerated his rearmament programme, and introduced conscription. The United Kingdom, France and Italy formed
17262-554: Was invaded by Germany. The United States started strategic planning to prepare for a full-scale offensive against Germany. At the end of September 1940, the Tripartite Pact formally united Japan, Italy, and Germany as the Axis powers . The Tripartite Pact stipulated that any country—with the exception of the Soviet Union—that attacked any Axis Power would be forced to go to war against all three. The Axis expanded in November 1940 when Hungary , Slovakia , and Romania joined. Romania and Hungary later made major contributions to
17399-410: Was a global conflict between two coalitions: the Allies and the Axis powers . Nearly all the world's countries —including all the great powers —participated, with many investing all available economic, industrial, and scientific capabilities in pursuit of total war , blurring the distinction between military and civilian resources. Tanks and aircraft played major roles , with the latter enabling
17536-425: Was a low-wing cantilever monoplane , featuring an oval-section metal semi- monocoque fuselage and a conventional tail unit with forward-placed tailplane . It was powered by a Rolls-Royce Griffon liquid-cooled piston engine, which drove a four-blade Rotol -built propeller . A large chin-mounted radiator was present to provide cooling for the engine. The Firefly had retractable main undercarriage and tail wheel,
17673-420: Was also licensed for use in the United States as the M1 , with the United States Army Air Corps (USAAC) and U.S. Navy , which concluded that a single HS404 is analogous to three .50 machine guns in firepower while weighing less than twice as much, planning to switch to the 20 mm calibre as soon as the gun could be produced in sufficient numbers. In 1941 a very large building program was established, along with
17810-472: Was extensively restored and made its first public appearance at Oshkosh in 2002. Restoration of WD518 used parts salvaged from WD828 which was written off after a crash into a cabbage field in Camden, New South Wales in 1987.WB518 as of July 2015 was then undergoing extensive rebuilding and is now in flying condition out of Gillespie Field, El Cajon, California. Other survivors include – in Australia: The Royal Thai Air Force Museum in Bangkok, Thailand has
17947-672: Was lighter and had a higher rate of fire (desirable in aircraft armament), although at the expense of some muzzle velocity. The shorter barrel meant that the weapon could be housed within the wing of a fighter plane, reducing drag and making the gun less vulnerable to freezing and mechanical stress. One of the main British fighters to use the Mk. V was the Hawker Tempest Mk. V Series II, which mounted two cannons in each wing. Ammunition types available included semi-armour piercing, incendiary (SAPI) and high explosive, incendiary (HEI). Around 42,500 Hispano cannons of various marks were manufactured by Birmingham Small Arms (BSA). The British version
18084-403: Was one of the first 10 Mk 6s built, but retained the earlier Mk 5 fuselage. It was originally delivered to the Royal Australian Navy's 817 Squadron and then served in 816 Squadron before being retired and ending up as a memorial on a pole in Griffith , New South Wales , Australia. WB518 was then purchased by American Eddie Kurdziel, a Northwest Airlines captain and former U.S. Navy pilot. WD518
18221-600: Was positioned aft of the wing's trailing edge . These positions provided better visibility for operating and landing, and both crew were provided with separate jettisonable canopies . The Firefly was equipped with an all-metal wing which could be folded manually, the wings ending up along the sides of the fuselage when folded. When in the flying position, the wings were hydraulically locked in place. The wing itself featured square tips and large Fairey-Youngman flaps , which provided relatively good handling while flown at low speeds. A total of four 20mm cannon were buried within
18358-403: Was postponed until the spring of 1940 due to bad weather. After the outbreak of war in Poland, Stalin threatened Estonia , Latvia , and Lithuania with military invasion, forcing the three Baltic countries to sign pacts allowing the creation of Soviet military bases in these countries; in October 1939, significant Soviet military contingents were moved there. Finland refused to sign
18495-402: Was repeatedly dispatched against Japanese-controlled islands up until Victory over Japan Day . The Firefly gained a level of public renown when the type became the first British-designed and -built aircraft to overfly the Japanese capital of Tokyo . During May 1945, in anticipation of a major naval offensive against the Japanese mainland, the Canadian government accepted a British offer to loan
18632-657: Was repulsed with heavy Italian casualties; the campaign ended within months with minor territorial changes. To assist Italy and prevent Britain from gaining a foothold, Germany prepared to invade the Balkans, which would threaten Romanian oil fields and strike against British dominance of the Mediterranean. In December 1940, British Empire forces began counter-offensives against Italian forces in Egypt and Italian East Africa . The offensives were successful; by early February 1941, Italy had lost control of eastern Libya, and large numbers of Italian troops had been taken prisoner. The Italian Navy also suffered significant defeats, with
18769-441: Was required to go through the bureaucracy of the League of Nations, which rendered it essentially toothless. The United States, concerned with events in Europe and Asia, passed the Neutrality Act in August of the same year. Hitler defied the Versailles and Locarno Treaties by remilitarising the Rhineland in March 1936, encountering little opposition due to the policy of appeasement . In October 1936, Germany and Italy formed
